Milling tool, and milling insert kit

Milling tool formed for gash milling, comprising

• a tool body that defines a rotation axis and has a first end, an opposite second end, and a peripheral surface that extends around the rotation axis between the first end and the second end;
• a large number of separated seats that are arranged one after the other in the tool body along a succession line;
• and
• a corresponding large number of replaceable milling inserts each one of which comprises an under side, an opposite upper side that forms a chip surface, a circumferential edge side that connects the upper side and the under side, an axis that extends through the upper side and the under side, and at least one primary main cutting edge and a secondary main cutting edge, which converge to each other and are formed where the edge side meets the upper side, each seat comprising a support surface for the receipt of one of the milling inserts each one of which projects from the tool body for cutting engagement with a gash of said workpiece,
• wherein that the milling inserts comprise outer milling inserts, which project from the tool body by a first length from the rotation axis, and inner milling inserts, which project from the tool body by a second length from the rotation axis, and
• wherein that the first length is considerably greater than the second length.
